Follicle-Stimulating Hormone Regulates igfbp Gene Expression Directly or via Downstream Effectors to Modulate Igf3 Effects on Zebrafish Spermatogenesis
Safian, Diego; Kant, Henk J. G. van der; Crespo, Diego; Bogerd, Jan; Schulz, Rüdiger W. (Peer reviewed; Journal article, 2017) -
Full production cycle performance of gene-edited, sterile Atlantic salmon - growth, smoltification, welfare indicators and fillet composition
Kleppe, Lene; Fjelldal, Per Gunnar; Andersson, Eva; Hansen, Tom Johnny; Sanden, Monica; Bruvik, Aina; Skaftnesmo, Kai Ove; Furmanek, Tomasz; Kjærner-Semb, Erik Nordtorp; Crespo, Diego; Flavell, Simon; Pedersen, Audun Østby; Vogelsang, Petra; Torsvik, Anja; Kvestad, Karen Anita; Olausson, Sara; Norberg, Birgitta; Schulz, Rüdiger W.; Bogerd, J.; Santi, N.; Edvardsen, Rolf Brudvik; Wargelius, Anna (Peer reviewed; Journal article, 2022)Using germ cell-free (GCF), sterile, dnd-knockout salmon for farming could solve the problems associated with precocious maturation and genetic introgression of farmed breeds into wild populations. However, prior to using ... -
Insulin-like 3 affects zebrafish spermatogenic cells directly and via Sertoli cells
Crespo, Diego; Assis, Luiz H. C.; Zhang, Yu Ting; Safian, Diego; Furmanek, Tomasz; Skaftnesmo, Kai Ove; Norberg, Birgitta; Ge, Wei; Choi, Yung-Ching; den Broeder, Marjo J.; Legler, Juliette; Bogerd, Jan; Schulz, Rüdiger W (Peer reviewed; Journal article, 2021)Pituitary hormones can use local signaling molecules to regulate target tissue functions. In adult zebrafish testes, follicle-stimulating hormone (Fsh) strongly increases the production of insulin-like 3 (Insl3), a Leydig ... -
Loss of stra8 Increases Germ Cell Apoptosis but Is Still Compatible With Sperm Production in Atlantic Salmon (Salmo salar)
Skaftnesmo, Kai Ove; Crespo, Diego; Kleppe, Lene; Andersson, Eva; Edvardsen, Rolf Brudvik; Norberg, Birgitta; Fjelldal, Per Gunnar; Hansen, Tom Johnny; Schulz, Rüdiger W.; Wargelius, Anna (Peer reviewed; Journal article, 2021)Entering meiosis strictly depends on stimulated by retinoic acid 8 (Stra8) gene function in mammals. This gene is missing in a number of fish species, including medaka and zebrafish, but is present in the majority of fishes, ... -
Pituitary Gonadotropin Gene Expression During Induced Onset of Postsmolt Maturation in Male Atlantic Salmon: In Vivo and Tissue Culture Studies
Crespo, Diego; Skaftnesmo, Kai Ove; Kjærner-Semb, Erik Nordtorp; Yilmaz, Ozlem; Norberg, Birgitta; Olausson, Sara; Vogelsang, Petra; Bogerd, Jan; Kleppe, Lene; Edvardsen, Rolf Brudvik; Andersson, Eva; Wargelius, Anna; Hansen, Tom Johnny; Fjelldal, Per Gunnar; Schulz, Rüdiger W. (Peer reviewed; Journal article, 2022)Precocious male maturation causes reduced welfare and increased production costs in Atlantic salmon (Salmo salar) aquaculture. The pituitary produces and releases follicle-stimulating hormone (Fsh), the gonadotropin ... -
Role of the Melanocortin System in Gonadal Steroidogenesis of Zebrafish
Navarro, Sandra; Crespo, Diego; Schulz, Rüdiger W.; Ge, Wei; Rotllant, Josep; Cerdá-Reverter, José Miguel; Rocha, Ana (Peer reviewed; Journal article, 2022)In teleost, as in other vertebrates, stress affects reproduction. A key component of the stress response is the pituitary secretion of the adrenocorticotropic hormone (ACTH), which binds to the melanocortin 2 receptor ... -

Andersson, Eva; Schulz, Rüdiger W; Almeida, Fernanda; Kleppe, Lene; Skaftesmo, Kai Ove; Kjærner-Semb, Erik; Crespo, Diego; Fjelldal, Per Gunnar; Hansen, Tom; Norberg, Birgitta; Edvardsen, Rolf B.; Wargelius, Anna (Others, 2024-01-30)Supplementary materials for "Loss of Fshr prevents testicular maturation in Atlantic salmon (Salmo salar L.)." published in Endocrinology, an Oxford academic journal https://doi.org/10.1210/endocr/bqae013 -
The initiation of puberty in Atlantic salmon brings about large changes in testicular gene expression that are modulated by the energy status
Crespo, Diego; Bogerd, Jan; Sambroni, Elisabeth; LeGac, Florence; Andersson, Eva; Edvardsen, Rolf; Bergman, Elisabeth Jonsson; Björnsson, Björn Thrandur; Taranger, Geir Lasse; Schulz, Rüdiger W. (Journal article; Peer reviewed, 2019)Background When puberty starts before males reach harvest size, animal welfare and sustainability issues occur in Atlantic salmon (Salmo salar) aquaculture. Hallmarks of male puberty are an increased proliferation activity ...
